You will be prompted to enter some security ;information. Your receiver must have your public key in order to decrypt your message. Once you have it, import the key into GPG. GPG uses public key encryption wherein you create a key pair: one private or secret key you keep to yourself and one public key you share with your correspondents or the world. … because we encrypted the file using his public key and only he has the corresponding private key which can decrypt the encrypted file.-recipient option means that you want to encrypt you message/ file for the person whose email id comes after --recipient. The benefit of public-private key encryption is that you can keep your public key out in the open, and use it from anywhere to encrypt files. In our scenario, there are two persons who want to communicate and they put their public keys on keyserver: It means that my_name@linoxide must import the public key of reader and vice versa. How about sending a secret file/ message in a more secure and trusted way? Public-key cryptography is based around the idea that with a pair of related keys (the private key and the public key), you can do some interesting one-way functions. Public key id can be extracted from the fingerprint of the public key. How to open the encrypted text. Why? GnuPG, also known as GPG , is a command line tool with features for easy integration with other applications. Public key, also known as asymmetric encryption involves two keys i.e. When you encrypt a file using a public key, nobody can decrypt except the recipient(only recipient has the private key). During my test, it seems doesn't work together. You must have the public keys of the intended recipients. Because our equipment is regularly connected to the internet and there is some communication, we need to protect the critical information we exchange.

Go to your terminal and type gpg --list-keys. public key and private key. If your friend is able to verify the file using your public key, then it assures that the file came from you because you signed the file with your private key and we know only your public key can decrypt/ verify it.gpg --verify signed-file# if the file is really from you, then your friend will get an output of something like gpg: Good signature We can also use decrypt option instead of --verify to verify signaturesgpg --decrypt singed-file# this will verify the file, decrypt it and display the original contents of the file to your standard output.gpg --output decrypted-file --decrypt singed-file# this will verify the file, decrypt and create a new file decrypted-file holding the original contentsThe decrypt flag works like this:– If the file it has no signature, it will just decrypt the file.– If it has a signature, but you don’t have the private key, it will decrypt the file but it will not verify the signature.– If it has a signature and you have the public key, it will decrypt and verify. Encryption provides confidentiality although signing binds the identity of the message source to this message. The armor flag is optional, it just outputs the file in ASCII armored/ normal text format.The output flag is necessary here. The sender of a message (reader@linoxide.com) can "sign" the message with his private key. The whole process can be described as follows: Adam wants to send a secret message to his friend Eve.Both have generated keys in their machine using the command gpg --gen-key.So Both have a set of “public key … Storing our partners’ public keys in a KeyStore gives us one extra layer of security. She will encrypt with Bob's public key, and sign with her private key. You can see that we don't use --sign parameter. Use –import option to import others public key. Encryption process always creates a file with.gpg or .asc extension. While terms like “public-key encryption” and “4096-bit RSA” might sound intimidating, you don’t really even need to understand how it works behind the scenes to use it. Microsoft Outlook Gpg4win comes with a GpgOL Outlook plugin, but unfortunately, as of this writing, it does not seem to work with Outlook 2016. John encrypts the input file using Bob’s public key. Only the holder of the private key can then decrypt the file. Signing ensures that the secret file is indeed from you. That file is encrypted and secured using your Public key of your key pair. $ gpg --encrypt-files --armor --recipient my_name@linoxide.com course car In order to securely send the message, Adam will need Eve‘s public key. The sender have to know his own passphrase which gives him access to his private key that he will use to sign encrypted messages, See that reader@linoxide need his own passphrase to sign the encrypted file that he will send to my_name@linoxide.com.
